Anotace obsahu normy

This document specifies the safety requirements and measures for manually loaded and unloaded
- single-end tenoning machines with a manual feed sliding table,
- single-end tenoning machines with a mechanical feed sliding table,
- single-end tenoning-profiling machines with mechanical feed,
- double-end tenoning-profiling machines with mechanical feed, also designed to be automatically either loaded or unloaded, or both, and
- angular systems for tenoning and profiling with mechanical feed
with maximum workpiece height capacity of 200 mm for single-end machines and 500 mm for double-end machines, capable of continuous production use, altogether referred to as "machines".
1.2 - This document deals with all significant hazards, hazardous situations and events as listed in Annex A, relevant to machines, when operated, adjusted and maintained as intended and under the conditions foreseen by the manufacturer including reasonably foreseeable misuse. Also, transport, assembly, dismantling, disabling and scrapping phases have been taken into account.
1.3 - The machines are designed to process in one pass one end or two sides, either opposite or perpendicular to each other, of workpieces made of
a) solid wood, and
b) materials with similar physical characteristics to wood (see ISO 19085-1:2021, 3.2); and
only the machines with mechanical feed, made of
c) fibre-cement,
d) rock wool and glass wool,
e) gypsum,
f) plasterboard,
g) matrix engineered mineral boards, silicate boards and sulfate boards,
h) composite materials with core consisting of polyurethane or mineral material laminated with light alloy,
i) polymer-matrix composite materials and reinforced thermoplastic, thermoset and elastomeric materials,
j) aluminium light alloy profiles, and
k) composite boards made from the materials listed above.
1.4 - This document is also applicable to machines fitted with one or more of the following devices or additional working units, whose hazards have been dealt with:
- sanding units;
- fixed or movable workpiece support;
- automatic tool changing;
- automatic workpiece returner;
- glass bead saw unit;
- hinge recessing unit;
- boring unit;
- dynamic processing unit;
- sawing unit installed out of the integral enclosure, between machine halves in double-end machines;
- foiling unit;
- coating unit;
- grooving unit with a milling tool installed out of the integral enclosure, between machine halves;
- brushing unit;
- gluing unit;
- sealing unit;
- dowels inserting unit;
- tongues inserting unit;
- inkjet marking unit;
- laser marking unit;
- labelling unit;
- workpiece back-up device (device that is either anti-chipping or anti-splintering, or both);
- quick tool changing system;
- post-formed edge pre-cutting unit;
- additional workpiece support (at either infeed or outfeed, or both);
- parallel infeed device on single-end machines;
- transversal infeed device on single-end machines;
- intermediate workpiece support on double-end machines;
- automatic infeed device;
- feed chain with dogs.
1.5 - This document does not deal with any hazards related to:
a) systems for automatic loading and unloading of the workpiece to a single machine other than automatic workpiece returner;
b) single machine being used in combination with any other machine (as part of a line);
c) use of tools, other than saw blades or boring tools or milling tools for grooving, installed between machine halves and out of the integral enclosure in double-end machines;
d) use of tools protruding out of the integral enclosure;
e) chemical characteristics of all materials listed in 1.3 c) to i) and their dust.
1.6 - This document is not applicable to machines intended for use in potentially explosive atmosphere nor to machines manufactured prior to its publication.
